Stent Designs and Implantation Techniques
The introduction of intracoronary stents has significantly influenced the current practice of interventional cardiology. The increase in the use of stents began with the publication of results of the BENESTENT (Belgium Netherlands Stent) and STRESS (Stent Restenosis Study) trials, which demonstrated significant reduction in restenosis rates in patients with discrete stenosis in large native arteries [1,2]. Acute complications of angioplasty, including abrupt vessel closure and emergency coronary bypass surgery, have also been reduced with the use of stents . Similar success with stents has been noted in angiographic subsets of complex lesions (eg, diffuse, tandem, severely calcified, restenotic, thrombotic, or ostial); in total occlusions, bifurcation lesions, saphenous vein grafts, and multivessel interventions, the combination of stenting and abciximab conferred additive long-term benefit with respect to death, myocardial infarction, and target vessel revascularization .
